Roxolid is the first Titanium-Zirconium (TiZr) alloy material designed specifically for dental implants. It is stronger than pure titanium1 and has excellent osseointegration properties.2,3,4 This combination of properties is unique in the market – there is no other metallic alloy which unifies high mechanical strength and osteoconductivity.
With outstanding mechanical properties, Roxolid Implants may allow you to use smaller-diameter implants with the same clinical performance as regular-diameter titanium implants.5 Smaller implants have the potential to preserve peri-implant structures and avoid invasive bone grafting procedures.
54 % of participants in a clinical non-interventional study stated that a bone augmentation procedure could be avoided due to the use of Roxolid Ø 3.3 mm Implants.7
With Straumann Roxolid Implants you have the ability to offer less invasive solutions8 to your patients that deliver faster treatment at a lower cost. These advantages have the potential to make dental implant treatments appealing to more patients.
Promoting faster osseointegration and providing higher predictability in stability-critical treatment protocols, the hydrophilic SLActive surface has become an advantage provided by the Straumann® Dental Implant System.
Most implant failures occur in the critical early period between weeks 2 and 4.9 A clinical study showed that SLActive Implants promote significantly greater osseointegration at 28 days than SLA® Implants.10 SLActive is designed to deliver high stability and has shown to be predictable in early treatment, giving you confidence in the treatment outcome.
Critical situations such as dehiscence defects are always a challenge and put success at risk. With SLActive, new bone volume and BIC are significantly higher (p<0.001) than SLA.11
Our SLA® surface was commercially launched in 1998 and is one of the most documented rough surfaces in implantology. The SLA® surface is produced using a large-grit sandblasting technique that generates a macro-roughness on the titanium surface. This is followed by acid-etching that superposes a micro-roughness. The resulting topography offers an ideal structure for cell attachment.
Straumann SLA surface is one of the most documented surfaces in dental implantology.
In these long-term studies, survival rates reached between 95% to 99%12,14,15 and even in patients with moderate or severe periodontal diseases an implant survival rate of 97% was reported.9 SLA surface shows low prevalence of peri-implantitis.14
